Cosmetic compositions comprising latex film formers

ABSTRACT

Disclosed are cosmetic compositions comprising at least one latex-film former chosen from at least one acrylate copolymer and derivatives thereof, and at least one coalescent and/or plasticizer.

FIELD OF THE DISCLOSURE

The disclosure relates to cosmetic compositions comprising (1) at leastone latex film former, and (2) at least one coalescent and/orplasticizer. Latex film formers useful in various embodiments of thedisclosure may be chosen from acrylate copolymers and derivativesthereof. Cosmetic compositions according to various embodiments of thedisclosure may have improved properties, such as improved water- and/oroil-resistance, shine, adhesion, hardness, and/or long wear.

BACKGROUND

Film formers, coalescents, and plasticizers are well-known in thecosmetic field. Inclusion of a film former in a cosmetic composition canimprove various properties, such as, for example, shine, adhesion, andlong wear. It is also known that inclusion of a coalescent agentpromotes the coalescence of polymer particles in an aqueous dispersion,and inclusion of a plasticizer makes it possible to plasticize a polymerin an aqueous dispersion.

The use of latex film formers in cosmetic compositions is also known,for example, in mascara, hair styling products, topical foundation,sunscreen compositions, and water-based nail enamel. In particular,latex and latex blends have been used to provide extended-wearproperties of the cosmetic product into which they are formulated. Forexample, conventional washable mascara compositions use latex filmformers in combination with an oil-in-water emulsion.

However, it has been found that cosmetic compositions having filmformers may have less than satisfactory properties. For example, nailvarnish compositions are known which comprise aqueous dispersions ofparticles of a film-forming polymer, wherein the film may exhibit pooradhesion to the nail and/or may not be sufficiently bright.

There is a desire in the cosmetic industry to provide consumers withproducts having improved properties such as improved shine, adhesion,and long wear. As such, there is a continuous need to invent novelcosmetic compositions which demonstrate one or more improved property.

It has now been surprisingly discovered that by incorporating (1) atleast one latex film former, and (2) at least one coalescent and/orplasticizer into cosmetic compositions, cosmetic properties such aswater- and/or oil-resistance, shine, adhesion, hardness, and/or longwear can be improved.

DESCRIPTION OF EXEMPLARY EMBODIMENTS
